The beneficial exercise is weight lifting.
The scientists have found that HDL functioned better in the men who have a regular weight-lifting program, even if they are overweight.
The research showed that overweight exercisers’ HDL is just as good as the HDL cholesterol circulating in thinner exercisers. Both groups’ HDL performs significantly better than those who don’t exercise.
This study suggests that regular weight training may improve HDL function and protect against heart disease, even in people who remain overweight.
